To all whom may om.- I

Be it known that 1, WILLIAM F. HUNTER,

a citizenof the United States, residing at Arcata, in the county of Humboldt and 5 State of California, have'i'nvented a new and useful Gaseous-Fuel Mixer, of which the followingis a specification.

The. present invention relates to an at tachment for the cylinders of internal combusti'on engines, for atomizing the fuel or mixture, to break the same into minute particles, and to vaporize the fuel. It is the object of the .invention to provide a an extremely-simple and inexpensive device 5 of that nature, which can be readily applied, and which will fulfil its 'oflice in a practical and efficient manner.

WVith the foregoing and other objects in view, which will be apparent as the nature of the'inv'ention is'better understood, the

invention resides in theprovision of'a screen or foraminous member of novel construction for attachment to an engine cylinder, being understood that changes in shape and portion of an engine cylinder, showing the device applied,

Fig. 2'is a diagrammatical end view of the screen I endthereo prior to the closing of the inner Fig. 3' is a similar view. showing the inner end of the screen bent or formed to close it. Fig. 4 is a section of the line 4- in- Fig. 2, this view being diagrammatical for 40 sake of clearness, the illustration of the wire or other suitable shape, having one end mesh being avoided.

-. In the drawing, there is illustrated a portion of an engine cylinder 1, havin the inmunication with the chamber 2 for sup .plying the carbureted air thereto.

In carrying out the invention, there is provided a screen 4: of cylindrical, tubular open and provided with an .outturned flange.5 clamped betwcenlthe cylinder and r into a line spray,thereby'atomizing the same, to enhance the combustion of the fuel withair therethrough into the chamber 2 and 5 details can be made within the scope of what.

in the cylinder. Furthermore, the screen in being associated with the "cylinder itself, will be heated thereby, and the mixture in flowing 'through the screen will be heated, to vaporize-the fuel, and thereb facilitating the combustion thereof. he outer open-end of the screen is clamped: between the cylinder and manifold, whereby the wall 'and inner closed end of the screen, which project into the chamber 2, are out of contact with the cylinder and surroundingjoarts, for the free flow of carbureted cylinder.

The'screen l can be inexpensively manufactured from tubular stock, one end of, the

screen being turned outwardly and bent or rolled upon itself to provide the flange 5, as seen in Fig. 4, and the other end offthe screen being bent back inwardly, as. at.6, to avoid afrayed edge. I To close the latter end of the screen, the same is folded inwardly, as at 7 ,in Veshaped folds fittin' to-.

gether, and providin wings 8Q The olds infitting together, wi 1 close the inner endof the screen, and in order to hold the wings 8 in place theyare foldedor bent back, as-at 9. -Having thus described 'the invention, what isclaimed as new is.:
